Fig.`5 is alongitudinal section on an enlarged scale illustrating `theindex shown in Fig. 4;

(Fig. 6 is a face view of the index with adjustable indicators applied thereto; and "MFig, is a longitudinal section of the parte shown in Fig. 6, on an enlarged scale, through some of the indicators. The index `comprises a frame A having inwardly bent flanges c, one at each side, andalpair of spaced guide rails a, c', be-

tween and parallel to thefianges a and preferablylocated underneath the said flanges, f forming therewith a pair of inwardly facing guide channels. A series of index slip Yholders B are mounted in the frame with their ends in said guide channels and slidable lengthwise thereof. Each slip holder B 'is made of transparent resilient material such as sheet Celluloid and comprises a closed relatively long and narrow front face and a pair of rearwardly and inwardly bent lips Z2, b', one overlapping the other, adapted to hold an index slip and forming therefor a transparent sheath.

The rear overlapping lip b is made ma`v terially'broader than the face of the sheath, thereby forming a Hap b2 which extends from'the rear of the sheath substantially fliatwise of the frame and underneath the Patented May 29, MMV?,

next adjoining sheath or sheaths. Said flap b2 preferably terminates short of the ends of the index slip holder B, and is preferably bent rearwardly a little asbest shown in Fig. 2, and extends between the guide rails a of the frame with only sufficient clearance to slide freely lengthwise of said guide rails. Said flaps 2) with their edges engaged and guided by the rails a, and lying underneath the adjoining sheath or sheaths, perform two main functions, namely, they serve to prevent the sheaths D from bending or bulging outward from the frame, which is particularly desirable in the case of wide frames carrying long sheaths, since each sheath is held flat in the frame not only by its own sti'ness -but is supported by the adjacent overlying sheath or sheaths; and in the form shown in Figs. 1, 2 and 3 in which the flaps b2 extend between the guide'rails a they serve to prevent the sheaths from twisting iu the frame or moving out of the line substantially perpendicular to the guide channels.

In the form shown in Figs. l and 5 the frame and sheaths B are substantially the same as the form shown'in Figs. l, 2 and 3, save that the guide rails a are omitted and the flaps 62 of the sheaths are made the full length of the sheaths, extending as before behind the adjacent sheath or sheaths. By this construction the advantage is secured by giving to each sheath the support of the adjacent sheath or sheaths to prevent the bending or bulging forward of the slieaths, and the advantage is also secured in a measure of preventing the sheaths from twisting in the frame, since the edges of the flaps engage the vchannels under the flanges c, thus affording a longer bearing surface than the ends of the sheaths u proper. ln this case the flaps Z220, which do not project between the guide rails, may be made more nearly parallel to the plane of the frame than in the forms shown in Figs. l, 2 and 3.

In the construction shown in Figs. 6 and 7, the frame and sheaths B2 are substantially similar to those already described, save that the flaps 252 vdo not extend to the ends of the sheaths B and into the guide channels of the frame, and arenot guided by guide rails. This construction secures the advantage of the mutual support given to the several sheaths by the iiaps extending flatwise underneath the adjoining sheath or sheaths, but does not secure the advantage ot guiding the sheaths and holding them against twisting when they are. shifted lengthwise ot the `trame.

An adjustable signal or indicator member oi suitable sheet material is shown in Figs. and 7, having` a signal portion d located between the liront :laee ot the index holder and the index slip (l, thence bent over one edge ot the index lslip l and projecting lat wise ol the index holder through the space between the retaining lips 7), b21, forming a tab portion by which the indicator member may be moved lengthwise of the slip holder. The signal portion of the indicator member may he provided with a sight aperture (Z2 through which a numeral or other character on the index slip C may be exposed and conspicuously brought to the attention of the user.

In any of the forms ot' slip holders the index slip C is inserted through the end of the sheath, and is removably held therein;

and obviously the adjustable signal or indiator `could be applied as described to any nt' the toi-ms of index slip holders.

1. An index comj'nising a `frame having inwardly facing guide channels, and a series ot index slip holders having their ends in said guide channels and slidable lengthwise thereof, said holders being made of transparent resilient sheet material, each comprising a closed front l'ace, a pair of rearwardly bent lips adapted to hold an index slip, and a flap extending from the rear of the sheath lfiatwise of the frame underneath the adjoining sheath or sheaths.

An index Comprising a frame having inwardly lacing guide channels, a pair of spaced guide rails between and parallel to said channels, and a series of index slip holders having their ends in said guide channels and slidable len j hwise thereof, said holders being made o transparent resilient sheet material, each comprising a closed front face, a pair of rearwardly bent lips adapted to hold an index slip, and a :flap extending from. the ear of the sheath atwise of the 'frame between said guide rails and underinath the adjoining sheath or sheaths.

2l. An index comprising a iframe having inwardly facing guide channels, and al series of index slip holders having their ends in said guide channels and slidable lengthwise thereof, said holders beingl made of transparent resilient sheet material, each comprising a closed front face. and a pair of rearwardly and inwardly bent lips adapted to hold an index slip, one lip overlapping thc other and being materially broader than the 'face of the sheath thereby Yforming a flap extending from the rear of the sheath liatwise of the frame underneath the adj oining sheath or sheaths.

4t. An index comprising a frame having inwardly facing guide channels, and a series of index slip holders having their ends in said guide channels and slidable lengthwise thereof, said holders being made of transparent resilient sheet material, each comprising a closed front face, and a pair ot' rearwardly and inwardly bent lips adapted to hold an index slip, one lip overlapping the other and bcingimaterially broader than the face of the sheath thereby forming a flap extending from the rear of the sheath liatwise of the frame underneath the adjoining sheath or sheaths, said flap terminating short of the ends of the index slip holder.

5. An index comprising a frame having inwardly facing guide channels, a pair of spaced guide rails between and parallel to said channels, and a series of index slip holders having their ends in said guide channels and slidable lengthwise thereof, said holders being made of transparent resilient sheet material, veach comprising a closed front face and a pair of rearwardly and inwardly bent lips adapted to hold an index slip, one lip overlapping the other and being materially broader than the face of the sheath, forming a flap extending from the rear of the sheath flatwise of the frame underneath the adjoining sheath or sheaths, said flaps being of a length corresponding to the distance between said guide rails and being rearwardly bent to extend therebetween.
